Summary of the Invention

Problems to be Solved by the Invention

[0006] A movable air conditioner that integrally includes a user-side unit and a heat source-side unit of this type may be lifted to a high position during transportation or the like. However, in the above-described conventional technology, there were points that needed to be improved regarding the structure for safely lifting the air conditioner.

[0007] Specifically, in a conventional air conditioner that integrally includes a user-side unit and a heat source-side unit, when lifting the air conditioner by hanging a lifting band or the like below the pedestal, there is a risk that the band or the like will slip and the air conditioner will fall.

[0008] Therefore, conventionally, when lifting an air conditioner to a high position, in order to prevent the slipping of a lifting band or the like, it is known to provide a plurality of shackle pins for fixing the band or the like to the base of the pedestal.

[0009] That is, a plurality of shackle pins are attached to the pedestal, a lifting band or the like is fixed to these shackle pins, the band or the like is connected to a lifting machine such as a crane, and the air conditioner is lifted.

[0010] In the configuration of lifting the air conditioner using shackle pins in this way, shackle pins are required, and fixing holes having sufficient strength for fixing the shackle pins need to be formed in the base of the pedestal. That is, a high-strength base with a thick plate thickness that can withstand the lifting load is used so that the pedestal does not deform during lifting.

[0011] Therefore, the conventional air conditioner that requires a pedestal formed from a thick plate material or the like and a plurality of shackle pins had a high production cost and was uneconomical. Also, during transportation, the work of attaching and detaching the shackle pins was required, and the workability was not good. Further, since a thick plate material or the like was used to ensure strength, the weight of the pedestal increased, and further, since the shackle pins were also attached, the air conditioner became heavy, and there was also a problem that the transportation work became difficult.

[0012] The present invention has been made in view of the above circumstances, and an object thereof is to provide a pedestal for an air conditioner and an air conditioner equipped with the same, which are lightweight, excellent in productivity, and capable of efficiently performing safe lifting work of the air conditioner.

Means for Solving the Problems

[0013] The pedestal for an air conditioner of the present invention is a mobile pedestal for an air conditioner on which a user-side unit having a user-side heat exchanger and a user-side fan and a heat source-side unit having a heat source-side heat exchanger, a heat source-side fan, and a compressor are placed. Four wheels are attached to the four corners of the base forming the lower part, and a band space for passing a lifting band is formed in the base for the four wheels. Inner side It is characterized in that. The band space is formed by notching and bending the lower part of the base It is characterized in that.

[0014] Further, the air conditioner of the present invention is characterized by including the pedestal for an air conditioner described above, the user-side unit placed on the pedestal, and the heat source-side unit placed on the pedestal and connected to the user-side unit via a refrigerant pipe.

Effects of the Invention

[0015] According to the pedestal for an air conditioner of the present invention, it is a pedestal for a mobile air conditioner on which a user-side unit and a heat source-side unit are integrally placed. Four wheels are attached to the four corners of the pedestal that constitutes the lower part. A band space for passing a lifting band is formed in the pedestal near the four wheels. By passing the lifting band through the band space provided near the four wheels of the pedestal, the air conditioner can be lifted. Therefore, since it is not necessary to attach a shackle pin to the pedestal as in the prior art, it is not necessary to provide a shackle pin attachment hole in the pedestal, and the plate thickness of the pedestal can be made thinner. Thus, the shackle pin becomes unnecessary, the manufacturing cost of the pedestal can be reduced, and the productivity of the air conditioner can be improved. In addition, the operator can efficiently perform a safe lifting operation without using a shackle pin.

[0016] Further, according to the pedestal of the air conditioner of the present invention, the band space may be formed by cutting and bending the lower part of the pedestal. Thereby, a safe lifting operation capable of preventing the band from slipping with a simple structure can be performed without adding a member for holding the band.

[0017] Further, according to the pedestal of the air conditioner of the present invention, the support member constituting the outer peripheral side of the lower part of the pedestal is formed of a plate material. The support member has a support plate part to which the wheel is attached, an outer plate part formed by bending the outer side of the support plate part upward, and an inner plate part formed by bending the inner side of the support plate part downward. The band space may be formed by cutting out the inner plate part. With such a configuration, it is possible to reduce the weight of the air conditioner by thinning the plate thickness of the pedestal while ensuring a safe strength capable of withstanding the loads of the user-side unit and the heat source-side unit. Therefore, productivity is improved, and the workability of lifting operations and transportation operations is also improved.

[0018] Further, according to the pedestal of the air conditioner of the present invention, the support member may include an upper plate portion formed by bending the upper side of the outer plate portion inward, and a lower plate portion formed by bending the lower side of the inner plate portion inward. Thereby, it is possible to further reduce the weight while ensuring the strength of the pedestal.

[0019] Further, according to the air conditioner of the present invention, it includes the pedestal for the air conditioner of the present invention described above, the utilization-side unit placed on the pedestal, and the heat source-side unit connected to the utilization-side unit via a refrigerant pipe and placed on the pedestal. Thereby, an air conditioner that is lightweight, excellent in productivity, safe, and can be easily lifted can be obtained.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, a pedestal for an air conditioner according to an embodiment of the present invention and an air conditioner including the same will be described in detail with reference to the drawings.

[0022] FIG. 1 is a diagram showing a schematic configuration of an air conditioner 1 according to an embodiment of the present invention. As shown in FIG. 1, the air conditioner 1 is a device for spot air conditioning that can be moved, and includes a utilization-side unit 10 and a heat source-side unit 20 placed on a pedestal 30 for an air conditioner. The air conditioner 1 is a movable and powerful spot air conditioner in which the utilization-side unit 10 and the heat source-side unit 20 are integrated.

[0023] The utilization-side unit 10 is a device that mainly cools or heats the air on the utilization side and supplies it. The utilization-side unit 10 has a configuration corresponding to the indoor unit of a general packaged air conditioner.

[0024] Specifically, the utilization-side unit 10 has a housing 11 which is a substantially box-shaped casing formed from a metal plate material or the like, and a utilization-side heat exchanger 12 and a utilization-side fan 13 which are components constituting a refrigeration cycle are provided inside the housing 11.

[0025] The heat-source-side unit 20 is a device that mainly radiates heat or absorbs heat from the air on the exhaust side. The heat-source-side unit 20 has a configuration corresponding to the outdoor unit of a general packaged air conditioner.

[0026] Specifically, the heat-source-side unit 20 has a housing 21 which is a substantially box-shaped casing formed from a metal plate material or the like, and a heat-source-side heat exchanger 22 and a heat-source-side fan 23 which are components constituting a refrigeration cycle are provided inside the housing 21.

[0027] The housing 11 of the utilization-side unit 10 has substantially the same outdoor installation specifications as the housing 21 of the heat-source-side unit 20, and the utilization-side unit 10 is Weather resistance manufactured with specifications that are substantially equivalent to those of the heat-source-side unit 20 in terms of heat resistance and waterproofness. Note that the sizes and shapes of the housing 11 and the housing 21 do not have to be the same. Also, different sizes and shapes can be adopted for the utilization-side heat exchanger 12 and the heat-source-side heat exchanger 22.

[0028] The utilization-side heat exchanger 12 of the utilization-side unit 10 is connected to the heat-source-side heat exchanger 22 of the heat-source-side unit 20 via the refrigerant pipe 28. Specifically, the utilization-side heat exchanger 12 and the heat-source-side heat exchanger 22 are connected via a compressor (not shown) that compresses low-pressure refrigerant into high-pressure, an expansion valve (not shown) that expands high-pressure refrigerant into low-pressure, the refrigerant pipe 28, and other refrigerant pipes (not shown), constituting a vapor compression refrigeration cycle circuit. As the refrigerant used in the refrigeration cycle, for example, HFC refrigerants and the like are adopted.

[0029] A pipe outlet 17 through which the refrigerant pipe 28 connected to the heat-source-side unit 20 is inserted is formed in the housing 11 of the utilization-side unit 10. The pipe outlet 17 is, for example, a knockout hole. The pipe outlet 17 is closed by a pipe outlet closing plate 29 with the refrigerant pipe 28 inserted therethrough.

[0030] A pipe outlet 27 through which the refrigerant pipe 28 connected to the utilization-side unit 10 is inserted is formed in the housing 21 of the heat-source-side unit 20. The pipe outlet 27 is, for example, a knockout hole. The pipe outlet 27 is closed by a pipe outlet closing plate 29 with the refrigerant pipe 28 inserted therethrough.

[0031] An air suction port 15, which is an opening for sucking air, and an air blowout port 16, which is an opening for blowing out air, are formed in the housing 11 of the utilization-side unit 10. A utilization-side heat exchanger 12 for performing heat exchange between the air sucked in from the surroundings and the refrigerant is provided at the air suction port 15. Thereby, for example, during the cooling operation, the air sucked in from the surroundings is cooled by the refrigerant evaporating in the utilization-side heat exchanger 12.

[0032] A utilization-side fan 13 for blowing out the air in the housing 11 that has exchanged heat with the utilization-side heat exchanger 12 to the outside is provided at the air blowout port 16. The utilization-side fan 13 is, for example, a propeller fan or the like, and is rotationally driven by a motor (not shown).

[0033] In the air conditioner 1 according to this embodiment, a particularly powerful user-side fan 13 is installed. Specifically, the user-side fan 13 is installed with a greater blowing capacity than the heat source-side fan 23. For example, it has a powerful blowing capacity to blow out air from the air outlet 16 at a wind speed of 5 m / s. As a result, in a large-scale workplace such as a factory, a strong blast with high straightness can be delivered far away, and only the working space can be efficiently cooled or heated aiming at the working space.

[0034] In addition, at the air outlet 16, a wind direction guide 14 for adjusting the flow direction of the air sent by the user-side fan 13 is provided. The wind direction guide 14 has an outer peripheral portion surrounding the outer periphery of the user-side fan 13, for example, in a substantially cylindrical form.

[0035] The inside surrounded by the outer peripheral portion of the wind direction guide 14 is an opening connected to the air outlet 16 through which air flows. Inside the wind direction guide 14, a variable wind direction adjustment plate (not shown) for adjusting the air flow is provided. With such a configuration, the air cooled or heated by the user-side heat exchanger 12 can be efficiently flowed toward the working space that requires it.

[0036] In the housing 21 of the heat source-side unit 20, a suction port 25 which is an opening for sucking air and a blowout port 26 which is an opening for blowing out air are formed. At the suction port 25, a heat source-side heat exchanger 22 for performing heat exchange between the air sucked from the surroundings and the refrigerant is provided. As a result, for example, during the cooling operation, the refrigerant in the heat source-side heat exchanger 22 is cooled and condensed by the air flowing in from the suction port 25. In other words, the air sucked from the suction port 25 is heated by exchanging heat with the refrigerant in the heat source-side heat exchanger 22.

[0037] At the blowout port 26, a heat source-side fan 23 for blowing out the air in the housing 21 that has exchanged heat with the heat source-side heat exchanger 22 to the outside is provided. The heat source-side fan 23 is, for example, a propeller fan or the like, and is rotationally driven by a motor (not shown).

[0038] In addition, an air direction guide 24 for adjusting the blowing direction of the air sent by the heat source side fan 23 is provided at the air outlet 26. The air direction guide 24 has an outer frame portion having a substantially rectangular shape, for example, surrounding the outer periphery of the heat source side fan 23, and is formed of a metal plate material, a resin plate material, or the like.

[0039] The pedestal 30 is a base that integrally supports the utilization side unit 10 and the heat source side unit 20. The pedestal 30 is formed of, for example, a steel plate, a channel steel, a groove steel, or other steel materials. A base 31 having an outer periphery that forms a substantially rectangular frame shape in a top view is formed at the lower part of the pedestal 30. The utilization side unit 10 and the heat source side unit 20 are fixed to the upper part of the base 31.

[0040] A utilization side unit installation base 32 for installing the utilization side unit 10 is formed on the pedestal 30. The utilization side unit installation base 32 is formed so as to protrude upward from the upper part of the base 31 so that the bottom of the utilization side unit 10 can be supported at a position higher than the bottom of the heat source side unit 20.

[0041] By providing the utilization side unit installation base 32 on the upper part of the base 31, the utilization side unit 10 is fixed at a high position. In this way, by providing the utilization side unit 10 at a high position, the position of the air outlet 16 of the utilization side unit 10 becomes higher, and cold air or warm air for air conditioning can be widely and efficiently blown out to the working space.

[0042] A drain pan 33 is provided on the upper part of the utilization side unit installation base 32. The drain pan 33 is a member for receiving the moisture that adheres to and drips from the utilization side heat exchanger 12 of the utilization side unit 10 and draining it to a water pipe (not shown). By providing the drain pan 33, the moisture dripping from the utilization side heat exchanger 12 of the utilization side unit 10 can be collected and preferably drained, and the scattering of moisture to the working space can be prevented.

[0043] In the vicinity of the four corners at the lower part of the pedestal 31, four wheels 34 located on the front, rear, left, and right of the gantry 30 are provided. The wheels 34 are, for example, casters having rubber wheels or the like, and the wheels 34 on one end side may be fixed wheels that can move in a predetermined one direction, and the wheels 34 on the other end side may be swivel wheels whose direction can be changed. By providing the wheels 34, the gantry 30 is configured to be movable while integrally supporting the user-side unit 10 and the heat source-side unit 20.

[0044] The user-side unit 10 and the heat source-side unit 20 are provided on the gantry 30 such that the suction ports 15 and 25 that each suck air face each other. That is, the user-side unit 10 and the heat source-side unit 20 are arranged back to back such that the user-side heat exchanger 12 side and the heat source-side heat exchanger 22 side face each other.

[0045] In other words, the user-side unit 10 and the heat source-side unit 20 are arranged such that the air outlets 16 of the user-side unit 10 and the air outlets 26 of the heat source-side unit 20 face outward so that each blows air in the opposite direction.

[0046] As described above, by arranging the user-side unit 10 and the heat source-side unit 20 such that the suction ports 15 and 25 face each other inward and the air outlets 16 and 26 face in the opposite direction so as to blow air in the opposite direction, efficient air conditioning for large-scale factories, logistics warehouses, etc. is realized.

[0047] That is, the cooled or heated air can be efficiently and strongly blown from the air outlet 16 of the user-side unit 10 to the working area to be air-conditioned. And, from the air outlet 26 of the heat source-side unit 20 facing the opposite side of the air outlet 16 of the user-side unit 10, the exhaust heat air for air conditioning can be discharged to a space away from the space that requires air conditioning.

[0048] In the air conditioner 1 according to the present embodiment, in the vicinity of the four wheels 34 of the gantry 30, a band space 46 for passing a lifting band 48 (see FIG. 4) when lifting the air conditioner 1 is provided.

[0049] Figure 2 is an enlarged perspective view of the main part of the base 30 of the air conditioner 1. As shown in FIG. 2, the band space 46 is provided in the vicinity of the four wheels 34 of the base 31 of the base 30, specifically, inside the four wheels 34. The band space 46 is formed by notching the inside of the lower part of the support member 40 of the base 31 and bending the vicinity of the notched part downward.

[0050] FIGS. 3(A) and 3(B) are cross-sectional views showing the schematic form of the support member 40 of the base 30. Referring to FIGS. 2 and 3(A), the support member 40 constituting the outer peripheral side of the lower part of the base 31 is formed of a plate material such as a galvanized steel sheet. Specifically, the support member 40 has a support plate portion 41 disposed substantially horizontally extending in the front-rear direction of the air conditioner 1, and the wheels 34 are attached to the lower surface of the support plate portion 41.

[0051] On the outer side of the support plate portion 41, an outer plate portion 42 is provided which is formed by bending the vicinity of the outer side of the support plate portion 41 upward by approximately 90 degrees, that is, substantially vertically. On the inner side of the support plate portion 41, an inner plate portion 43 is provided which is formed by bending the vicinity of the inner side of the support plate portion 41 downward by approximately 90 degrees, that is, substantially vertically.

[0052] That is, the support member 40 is bent so as to form a substantially Z-shaped cross-section. Thereby, a lightweight and sufficiently strong support plate portion 41 can be obtained. Also, as described above, since the air conditioner 1 does not need to be provided with shackle pin attachment holes in the base 30, the plate thickness of the support member 40 can be reduced.

[0053] With such a configuration, while ensuring sufficient strength to withstand the loads of the user-side unit 10 (see FIG. 1) and the heat source-side unit 20 (see FIG. 1), the plate thickness of the support member 40 can be reduced to lighten the air conditioner 1. Therefore, productivity is improved, and the workability of lifting work and transportation work is also improved.

[0054] Referring to FIG. 2, the band space 46 is formed by notching the inner plate portion 43 of the support member 40. Specifically, in the manufacturing process of the support member 40, a notch that will become the band space 46 is formed in the plate material that will become the support member 40. Then, the plate material with the notch formed is bent by pressing or the like to form the inner plate portion 43, and the band space 46 for safely holding the band 48 (see FIG. 4) is formed.

[0055] Also, referring to FIGS. 2 and 3(B), the support member 40 has an upper plate portion 44 formed by bending the upper side of the outer plate portion 42 inward by approximately 90 degrees, that is, approximately horizontally. Further, the support member 40 may have a lower plate portion 45 formed by bending the lower side of the inner plate portion 43 inward by approximately 90 degrees, that is, approximately horizontally. With such a configuration, while ensuring sufficient strength, the plate thickness of the support member 40 can be reduced to further lighten the gantry 30.

[0056] FIG. 4 is a view showing the attachment state of the band 48 when the air conditioner 1 is lifted. As shown in FIG. 4, by passing the band 48 through the four band spaces 46 provided in the vicinity of the wheels 34 of the gantry 30, the air conditioner 1 can be lifted together with the gantry 30.

[0057] As described above, the band space 46 is formed as a notch in the inner plate portion 43 (see FIG. 2) of the support member 40 of the base 31. Therefore, the slipping of the band 48 is suppressed by the inner plate portion 43. That is, the band 48 attached to the band space 46 is suppressed by the inner plate portion 43 and does not slip inside in the front - rear direction of the air conditioner 1. Thus, a safe lifting operation without slipping of the band 48 is performed.

[0058] In this way, by passing the lifting band 48 through the four band spaces 46, the air conditioner 1 can be safely lifted, and there is no need to attach a shackle pin to the pedestal 30 as in the prior art. Therefore, the shackle pin becomes unnecessary, and the hole for attaching the shackle pin also becomes unnecessary, so the manufacturing cost of the pedestal 30 can be reduced, and the productivity of the air conditioner 1 can be improved.

[0059] Also, the operator can lift the air conditioner 1 by attaching the lifting band 48 using the four band spaces 46 without using a shackle pin. That is, the operator can efficiently perform a safe lifting operation.

[0060] As described above, the pedestal 30 for the air conditioner according to the present embodiment and the air conditioner 1 equipped with the same are lightweight, excellent in productivity, and can be safely and easily lifted and moved. Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
